Hinged Reservoir Pump Layout for Left-Right Handlebar Mounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle hydraulic pumps for clutches and brakes require separate designs for the right and left sides of the handlebar, leading to increased costs and complexity.
Innovation Solution
A pump design with a hingedly mounted reservoir that can be positioned in two orientations, allowing the same pump to be used on either the right or left side of the vehicle handlebar, featuring a movable piston and a reservoir with a push button for actuation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate pumps are designed for the right and left sides of the handlebar, then the pump can be specifically optimized for each side, but the production cost and device complexity increase
Solution Approach 1:
The pump housing is designed with a universal structure that can accommodate the reservoir in two different orientations (right side and left side). The reservoir is mounted via a bracket that allows rotation between positions, enabling a single pump design to serve both sides of the handlebar, thus reducing the number of pump variants while maintaining side-specific optimization
Solution Approach 2:
The reservoir mounting bracket incorporates a rotation mechanism that allows the reservoir to be dynamically repositioned between right-side and left-side orientations. This dynamic adjustment capability enables a single static pump housing to support dynamic configuration changes, eliminating the need for separate right and left pump designs
2Reliability
If separate pumps are designed for the right and left sides, then side-specific requirements are met, but manufacturing cost increases
Solution Approach 1:
By designing a universal pump housing that can accommodate the reservoir in either orientation, the manufacturer produces only one type of pump housing instead of two separate variants. This universality reduces tooling costs, simplifies inventory management, and lowers per-unit manufacturing costs while still meeting side-specific performance requirements through the adjustable reservoir positioning
3Device complexity
If the reservoir is fixed in one position, then the pump structure is simpler, but the pump cannot be used on both sides of the handlebar
Solution Approach 1:
The reservoir mounting bracket is designed with rotational capability, transforming the static fixed-position mounting into a dynamic adjustable mounting. This allows the reservoir to be repositioned between right-side and left-side orientations, granting the pump versatility for both sides while adding only minimal rotational mechanism complexity to the mounting structure

Implementation Method 1
the reservoir is hingedly mounted with respect to the housing of the piston, being positionable in at least a first or a second position
Implementation Method 2
a reservoir in which a fluid is housed that drives the piston movement inside the housing

AI summary
The pump for vehicle clutches or brakes comprises a piston (1) movable inside a housing (2); and a reservoir (3) in which a fluid is housed to drive the movement of the piston (1) inside the housing (2), wherein the reservoir (3) is hingedly mounted with respect to the housing (2) of the piston (1), being positionable at least in a first or second position. It provides a pump for vehicle clutches or brakes that can be used on either the right or left side of the vehicle.
